Latest In vivo magnetic resonance spectroscopy Stories

Nuclear magnetic resonance (NMR) is one of the best tools for gaining insight into the structure and dynamics of molecules because nuclei in atoms within molecules will behave differently in a variety of chemical environments. Nuclei can be thought of as tiny compasses that align when placed in the field of a strong magnet. Similar to magnetic resonance imaging (MRI), conventional NMR uses short pulses of radio waves to drive nuclei away from equilibrium and a 'signal' emerges as nuclei...

Magnetic resonance spectroscopy can distinguish between neurological diseases in patients without clear symptomsA team of American scientists claim that a new method of testing for neurological diseases could provide doctors with a rapid and non-invasively method of diagnosing degenerative disorders. The research, published in The journal of Comparative Neurology, reveals that Magnetic Resonance Spectroscopy (MRS) can distinguish between different disorders in patients, allowing earlier...

MR spectroscopy reveals signature of disease process, could guide treatment of many conditionsMagnetic resonance (MR) spectroscopy "“ which analyzes the biochemistry rather than the structure of tissues "“ may someday be able both to pinpoint the precise location of prostate cancer and to determine the tumor's aggressiveness, information that could help guide treatment planning. In the January 27 online issue of Science Translational Medicine, Massachusetts General Hospital (MGH)...

The Atlantic blue crab, Callinectes sapidus, long prized as a savory meal at a summer party or seafood restaurant, is a multi-million dollar source of income for those who harvest, process and market the crustacean along the U.S. Atlantic and Gulf coasts. Unfortunately, the blue crab population has been declining in recent years under the assault of viruses, bacteria and man-made contaminants. The signs of the attack often are subtle, so researchers from the National Institute of Standards...

Detection of ultra-low concentrations of cancers and other clinical targetsA new technique in Magnetic Resonance Imaging dubbed "Hyper-SAGE" has the potential to detect ultra low concentrations of clinical targets, such as lung and other cancers. Development of Hyper-SAGE was led by one of the world's foremost authorities on MRI technology, Alexander Pines, a chemist who holds joint appointments with the Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California,...

The brain reacts quickly to alcohol. "Our study provides evidence for alternative energy utilization upon alcohol ingestion, i.e. the brain uses an alcohol breakdown product instead of glucose for energy demands," explains Dr. Armin Biller of the working group for cerebral metabolism at the Department of Neuroradiology at Heidelberg University Hospital (Medical Director: Prof. Dr. Martin Bendszus). The harmful effect also sets in quickly. During the experiment, the concentration of...

A clinical decision model which uses MR spectroscopy to help physicians differentiate between recurrent tumors and changes in the brain tissue due to radiation treatments, may help patients avoid invasive procedures and treatments, according to a study performed at the University of Michigan Health System in Ann Arbor, MI.The study included 33 patients who had undergone radiation treatment for brain tumors and had MRI examinations that showed new lesions (either a recurrent tumor or radiation...

U.S. and French scientists say they've developed a new understanding of a process called adiabaticity that's used to control atoms in magnetic resonance. Adiabatic processes are what physicists and engineers use to control atoms in nuclear magnetic resonance spectroscopy and during magnetic resonance imaging. Researchers at Ohio State University and three French institutions -- the National Center for Scientific Research, the University of Lyon and the University of Orleans -- said their...
